It's perfect for hand applique, hand embroidery, hand quilting, cross stitch, embellishment, handmade lace, machine applique, blanket stitch, machine embroidery (especially for designs that use a longer stitch length), machine art quilting, Sashiko, redwork, lower looper serging, and longarm quilting. Made in Italy.
Needle recommendation: 90/14 or 100/16. Use a thinner weight thread like a 40wt in the bobbin.
